JACKSON, Wyo. — On Friday, Dec. 15, Teton County introduced that the U.S. Army Corps of Engineers (USACE) Walla Walla District accomplished rehabilitation work on Evans Levee, situated close to the doorway to the Snake River Canyon, with the removing of over 2500 tons of concrete rubble.
The completion of the levee mission will make it safer for boaters and extra structurally sound to deal with heavy river flows throughout spring runoff.
According to Teton County, USACE started work in 2022 to take away the concrete from the face of Evans Levee, which included sidewalk slabs, rubble and chunks of building basis. The items ranged from roughly 20,000 to 40,000 kilos and principally included rebar and different metal protrusions, creating hazards to boaters.
Throughout the rehabilitation course of, the Walla Walla District placed 2,700 tons of grime on the levee to enhance the slope for riprap (rock) placement and 6,500 tons of basalt riprap, a extra appropriate levee overlaying, to interchange the concrete rubble. The new riprap will enhance the levee’s resistance to heavy spring flows produced from snowmelt, Teton County stated in a press release.
The unique concrete rubble was placed on the Evans Levee as riprap within the Nineteen Seventies. Portions of the levee had been then constructed in 1969, 1976 and 1996. In 1986, the Walla Walla District took over the operation and upkeep of Evans Levee.
The Walla Walla District maintains the Evans Levee, together with 23 different levees within the Jackson space, totaling greater than 33 miles.
